The mod_log_sdb module allows Apache to log to any
SQL database supported by LibSDB, the Simple
Database Library. It requires very little manual
configuration; in fact, a single line in
httpd.conf is sufficient.

mod_log_spread is a patch to Apache's mod_log_config, which provides an interface for spread to multicast access logs and per-vhost logs. It utilizes the group communication toolkit Spread for reliable multicast transport. mod_log_spread was developed to solve the problem of collecting consolidated access logs for large web farms. In particular, the solution needed to be scalable to hundreds of machines, utilize a reliable network transport, allow machines to added or dropped on the fly, and impose minimal performance impact on the Web servers.

mod_myvhost is an Apache module for dynamically configured name-based mass virtual hosting with PHP. Virtual host configurations and PHP settings are stored in a MySQL database. There is no need to have every vhost in apache's configuration file, or to restart apache after a configuration change. It is able to change PHP settings dynamically for any vhost. By default, it sets open_basedir as the vhost's rootdir, but you can change almost any parameter that exists in php.ini. For example, you can turn on safe_mode or register_globals for a particular vhost.

mod_ntlm is a NTLM authentication module for Apache / Unix. NTLM is often used in Microsoft based Intranets to pass user's credentials from their workstation-logon to the web server (user authentication without password boxes). Password validation is done through Windows NT or Samba machines over TCP/IP.

Generally, mod_ocaml is a flexible apache module for use of INRIA's powerful OCAML interpreter as a Web scripting language (with functional and imperative features). Simply embed OCAML code between HTML on your pages, like you do with PHP, mod_perl, etc. After modifying some settings, you can use almost any interpreter for providing dynamic content on your HTML pages.

The Apache/Perl integration project brings together the full power of the Perl programming language and the Apache HTTP server. With mod_perl it is possible to write Apache modules entirely in Perl. In addition, the persistent interpreter embedded in the server avoids the overhead of starting an external interpreter and the penalty of Perl start-up time.
